*The qemu-system-arm installed by Ubuntu 10.04 (qemu_0.12.3+noroms-0ubuntu9.16_i386, qemu-kvm-extras_0.12.3+noroms-0ubuntu9.16_i386) doesn't work even on qemu ARM disk image (arm-test-0.2.tar.gz). But it works on other images(e.g. 2.6.33 versatilepb image), reason unknown.

You can also use -net nic,model=? to get a list of valid network devices that you can pass to the -net nic option. [If you'd like to know all of the virtual network devices that are currently provided in QEMU, a search for "NetClientInfo" in the source code may be useful.]

Ever done a "git annotate" that stops at 2.6.12-rc2, and wanted to see the full history? Here's an repository that goes all the way back to 0.0.1 (through bitkeeper and all those old tarballs), which otherwise works as normal (git pull updates it from Linus's tree, you can committo it and branch from it, etc)

kernbench is a CPU throughput benchmark. It is designed to compare kernels on the same machine, or to compare hardware. It runs a kernel compile at various numbers of concurrent jobs: 1/2 number of CPUs, optimal (default is 4xnumber of CPUs), and maximal job count. Optionally it can also run single threaded. It then prints out a number of useful statistics for the average of each group of runs.

is coming from the use of the libcap library. A newer version of the libcap library (called the "libcap2-dev" package on some Linux distributions) is now available.

To remove the above warning, you will need to update/install the newer libcap2 package on your system, and re-build proftpd (using version 1.3.2rc1 or later) in order to compile and link against the newer libcap library.
